It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-98266 in the wild and no public exploit code.\n\nAffected product: Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-98266/ (Markdown: https://insights.sbomify.com/CVE-2026-98266/index.md)","id":"CVE-2026-98266","markdown":"https://insights.sbomify.com/CVE-2026-98266/index.md","name":"CVE-2026-98266","record":{"aliases":["AZL-106260","BELL-CVE-2026-98266","DEBIAN-CVE-2026-98266","GHSA-4mg3-v7f5-c2hj","UBUNTU-CVE-2026-98266"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel ALSA","requires_auth":"none","summary":"A use-after-free in the Linux kernel ALSA core allows local attackers to execute arbitrary code or escalate privileges via asynchronous card release.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: core: Fix potential UAF after asynchronous card release\n\nUsually a sound driver releases the resources assigned to the card via\nsnd_card_free(), and it synchronizes with the whole release procedure.\nHowever, when the card is released asynchronously via\nsnd_card_free_when_closed() like USB-audio driver, the situation is\nslightly different; although the snd_card_disconnect() call at the\ndisconnection guarantees that any newer accesses will be gated, the\nin-flight tasks might be still accessing to the underlying card-\u003edev\ndevice even after the disconnection, which would cause a\nuse-after-free in the end, as reported by fuzzers.\n\nFor addressing the bug above, this patch takes the refcount of\ncard-\u003edev at initialization of the card object, and releases at its\ndestructor.
